Không trả lời được đâu!Các bạn giúp mình với.
356 = 300 + 50 + 6 3243 = 3000 + 200 + 40 + 3
= 3.100 + 5.10 + 6 = 3.1000 + 2.100 + 4.10 + 3
= 3.102 + 5.10 + 6 = 3.103 + 2.102 + 4.10 + 3
abbc = a000 + b00 + b0 + c
= a.1000 + b.100 + b.10 + c
= a.103 + b.102 + b.10 + c
Ta có:
*356=3.100+5.10+6=3.102+5.10+6
*3243=3.1000+2.100+4.10+3=3.103+2.102+4.10+3
*abbc=a.1000+b.100+b.10+c=a.103+b.102+b.10+c
